It is based on a hybrid methodology that combines both Logistic chaotic attraction points and artificial neural network (ANN) models. At first, to calculate the Logistic chaotic attractor according to falling and total solar cycle length for

Based on endogenous growth theory, this study empirically tests the standard growth model consisting of gross domestic product (GDP) per capita as a dependent variable and human capital formation, investment in physical capital and labor force as independent variables. Autoregressive distributive lag (ARDL) bound testing approach to cointegration is used to check the long run equilibrium relationship between the variables included in the model. For checking the causal relationship between economic development and human capital formation, pairwise Granger causality test is used for time series data (1972 to 2009). The results of the cointegration show that the variables are cointegrated. They have long run stable equilibrium relationship. The results of the causality test show a bidirectional causal relationship between economic development and human capital format...
